The original stamped 7° valve lock served the industry well until drag racers discovered the ''Vasco Jet'' valve spring in the early 1970's. The use of these previously undreamed of spring pressures caused periodic failures as the little 7° lock was vulnerable to extrusion through the retainer. Drag race engine builders seized upon the evidence of locks pushed through retainers as proof of the inadequacy of the 7° design. This is how the 10° lock came to be. In reality, the problem with the 7° lock was not the angle. The 7° lock was simply too skinny to provide enough resistance to being pushed through the retainer. Meanwhile, circle track engine builders responded to the same challenge with a Super 7° lock that maintained the superior clamping properties of the original 7° piece but overcame the extrusion problem with increased lock thickness. Manley Performance supports both 10° and 7° systems with the highest quality locks and retainers in the industry, manufactured of both steel and titanium.
